$ Frontend -> Backend API -> Agent -> LAN Broadcast -> Target Device Frontend -> Backend API -> Agent -> LAN Broadcast -> Target Device Frontend -> Backend API -> Agent -> LAN Broadcast -> Target Device - Devices are asleep when you need them - WOL tools are often single-host and not built for organization - Dockerized services may not have direct LAN broadcast access (especially on Windows/macOS Docker Desktop) - Existing setups rarely provide proper inventory, auth, and operational visibility - Organize devices and agents into clusters - Associate each device with multiple agents - Send a wake request for one device or an entire cluster - Fan out wake dispatch through every associated online agent - Track agent health through registration and heartbeat state - Centralized device, cluster, and agent management - Multi-agent wake dispatch for higher reliability - Cluster-level wake orchestration for batch operations - FastAPI backend with clear API boundaries under /api - React + TypeScript frontend for daily operations - Lightweight Go agent with: Auto-registration Heartbeats Network/broadcast detection Token-protected /wol endpoint - Auto-registration - Network/broadcast detection - Token-protected /wol endpoint - Local authentication and OIDC support - Cross-platform agent support (Windows, Linux, macOS) - Open-source and MIT licensed - Auto-registration - Network/broadcast detection - Token-protected /wol endpoint - You keep ownership of your infrastructure and identity configuration - You decide where wake-capable agents run (close to your LAN targets) - You avoid cloud lock-in for a core internal operation - You can deploy quickly with Docker Compose and scale out agents as needed - You get a practical architecture for mixed environments instead of a toy WOL sender - The backend does not send magic packets directly - Agents perform wake operations from the host network - Wake requests can traverse multiple online agents for resiliency - Homelab operators managing NAS, hypervisors, and utility nodes - Developers who need workstations online on demand - Teams with shared build/test machines - Ops engineers who want predictable wake workflows with visibility - GitHub: https://github.com/kotsiossp97/powerbeacon - Documentation: https://kotsiossp97.github.io/powerbeacon/ - Issues and feedback: https://github.com/kotsiossp97/powerbeacon/issues
